※建立EtherChannel的條件

  1. 所有被綁定的port屬於同一個VLAN
  2. 如果是trunk mode,所有PORT都要同一個native VLAN
  3. SPEED和DUPLEX要一樣

※負載平衡類型

 Method Hash Input Hash Method Switch Model
 src-ip  Source IP bits ALL
dst-ip Destination IP bits ALL
src-dst-ip Source & Destination IP XOR ALL
src-mac Source MAC bits ALL
dst-mac Destination MAC bits ALL
src-dst-mac Source and Destination MAC XOR ALL
src-port Source Port bits 6500, 4500
dst-port Destion Port bits 6500, 4500
 src-dst-port Source & Destination Port XOR 6500, 4500

※建立EtherChannel的協定

Negotiation Mode   Negotiation Packet Sent Characteristics
PAgP LACP    
On On No All ports channeling
Auto Passive Yes Waits to channel until asked
Desirable Active Yes Actively ask to form a channel

※LACP的Standby Interface使用higher priority
